I don't know how wiping the cache partition would delete the browser but it should still be on the phone somewhere. you can always download another from the play store
If it's not there then, as belodion said, use Play to install one. (I suggest Firefox, but that's my personal; preference. If you have a preference, install yours. Or install one, play with it, if you like it, keep it. If you don't, uninstall it and install another one. Wash, rinse and repeat until you have one you like.)
